It's a different question, but an interesting one. The 2.0T turbos have a combined manifold and turbine housing, so you'de have to change the whole manifold, not just the turbo.
Whether or not the 2.0T has the same port spacing, bolt pattern and mating surface, I don't know, but would doubt. You'd certainly have to change the dp and turbo inlet and outlet piping.
Whether there would be any gains, whether it would be laggy or not is anyne's guess.
You'd be looking at a world of pain, for sure.
